Currently, modem status interrupt software processing is not implemented.
So, if enabling modem status interrupt, the interrupt processing is not
processed correctly.
(pch_uart device has auto hardware flow control function. So, pch_uart driver
doesn't have to control modem status interrupt.)
This patch deletes the code.
